-------------------------------------

Thank you for comments.
I think this is because of the reason as follows:
First, BufferedMutation#flush is processed synchronously,
and a batch request (MultiRequest) is created from a buffered mutations.
Then, RegionServer processes a MultiRequest as a
minibatch(HRegion#doMiniBatchMutation) that updates the timestamp of each cell
to currentTime if Mutation has HConstants.LATEST_TIMESTAMP(by default).
This operation apply all mutations in minibatch, therefore all cells has
same timestamp.
Since the HBaseStore#put create the Delete and Put as the MultiRequest,
Puts are invisible.

I'm sorry for my poor english :(
I made this fix as a possible solution. (HACK)

However, does not pass testDeleteByQueryFields yet.
This is known issue GORA-472. I will create(reopen) the pull request for
GORA-472 later.
and I am trying to run all test..
